Built‑in function

FBC21 advanced fieldbus controller undertakes high‑load fieldbus communication management for Foxboro I/A‑Series DCS FBM subsystem. It processes mass real‑time process data and supports access of large‑quantity remote FBM I/O stations. Hot‑swap function supports online module replacement and reduces plant downtime risk. Status LED facilitates on‑site fieldbus network inspection,widely applied for large‑scale DCS cabinet FBM‑subsystem control‑unit replacement maintenance in petrochemical,chemical and power‑plant facilities.

Product Brief

FBC21 belongs to Foxboro I/A Series legacy DCS fieldbus‑controller spare‑part family,obsolete original baseplate‑mount high‑capacity fieldbus controller component. Must match with corresponding baseplate assembly. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
